Electric energy is crucial for Earth and its cycles. The Globe is like a huge electric circuit. The Ionosphere layer of the atmosphere is positively charged and the Earth is negatively charged. The difference is of about 250,000 volts. If we could make the connection, through a conductor, between Earth and Ionosphere... |

Air contamination is bad for our health, that is clear: it causes an array of respiratory diseases, from asthma to lung cancer, if chronic. But a new research published in the "Proceedings of the National Academy of Sciences" shows it may hit where men are most hurt: their fertility. Mice living in areas with pollute... |

If you ever had a flat tire in the middle of nowhere, no spare and waited for more than two hours for someone to come and rescue you, then you might consider throwing the car's wheels right to the garbage container and buy yourself a pair of tweels.

1.The Earth is wrapped in a layer of gas called atmosphere. Atmosphere is tied to Earth by gravitation, so that it cannot disperse in the space. It is 500 km (300 mi) thick, being made of a mix of about 10 gases, called air. The air is made by nitrogen (78 %), oxygen (21 %) and other gases (argon, carbon dioxide, he... |

We are in the middle of a dreadful global warming that could melt all the Arctic glaciers by the middle of this century. Humankind is in a struggle to find all kind of technologies reducing the emissions of greenhouse effect gases. And one of the main emitters of these gases are cars.

Ice has long been valued as a means of cooling, before the invention of air conditioning units. Although the latter are more efficient, they also cause pollution and eat up massive amounts of electricity, which is mostly produced by burning coal and oil, which also pollute the environment.Some office towers and buil... |

In the first 9 months of our lives, we live like aquatic beings in the womb of the mother. But that's all. After that, the water environment is forbidden for us: we can swim at the surface, but less under water. One famous and remarkable example (but not the only one) are the famous Japanese ama woman divers. Am... |

You've probably heard than when a lightning storm catches you on open ground, you shouldn't take cover under a tree. That's true. Since lighting often strikes the highest spot in an area, ducking below a tall tree is definitely not a good idea, since you'll probably be struck in the same time.If ... |

A new discovery shows that bricks made from fly ash are very stable and much safer than initially thought. When they were first discovered, many theorized that these special bricks would leak small amounts of mercury into the atmosphere, thus posing a major threat for humans.A team of researchers, led by Henry Liu, ... |
